0n@M,-f i y i rangenneiit of metal .Strom `that shown in 55 Be it known thatLWIIMAM N. OMIM, a citizen `off United States, and resident of Michigan City, county of Laporte, and State of Indiana, have invented Vcertain new and useul Improvements ini CanBodieS, of which the lfollowing is ai specification, and which are illustrated inthe actzompanyingA1 drawings, forming a part thereofg L he invention'relates to improvements in car bodies. lThe lobject of the invention is the placingo the ymetal in :the structurefof a car body to the best advantage for the resistance to stresses andlttor increased life under corrosion. A gfurther object of the invention isthe ,provision of a car body fhaving stiening `means which sh-all ive more than the usual stiifness to a carbo y in proportion `te the amount off metal utilized.

In the aecompan ling drawings:

Figure i "is Taf-si`I eview of one end of a car body, the invention being illustrated as applied to a gondola car body;

Fig. 2 is a vertical transverse section taken on the line 2-2 of Fig. 1, the side sill being shown in a different position from that of Fig. 1;

Fig. 3 is a view similar to Fig. 2 of the bottom portion of a stake and web plate, showing a di'erent arrangement of metal.

Fig. 4 is a side view of one corner of a car body, showing a different structure of corner from that illustrated in Fig. 1,

Fig. 5 is a vertical section taken on the line 5-5 of Fig. 4,

Fig. 6 is a transverse section taken on the line 6-6 of Fig. 4, and

Figs. 7 and 8 are vertical sections on an enlarged scale taken on lines 7--7 and 8-8 respectively of Fig. 6 the web plate being omltted.

A side web plate is shown, indicated at 1, and it will be observed in Fig. 2, that this plate is thickest at the bottom edge and tapers gradually to its thinest portion at the upper edge. Riveted to this web plate is shown a stake or sti'ening rib 2, which stake is made up of two {ianges 3 and a central raised rib 4. As shown, in Fig. 2, the metal of this stake is thickest at its bottom 5, both in its rib portion and in its flanges, and tapers as does the metal of the web plate.

In Figs. 3 to 8 inclusive a different ar- Fiig'.y 2, and one coming within the Vpurview of .my invention, :is shown. 'lin' .thiis form of the invention the greatest fthielrnesslof 'metal in theweb lplate and in fthe `ilange and rib ofv thestakes 'shown at the `point 20 .su'b- 60 stantia'lly at :the ilgenel off the fear floor f2.1. This isethe actua'l pointroffthe 'greatest'bending stress as 'well as 'the eatest probable corrosion of @the web :p ate. From this point-the Vmetalof both stake and yweb-:plate tapers both` upwardly and downwardly.

The lcorner late shown at 6, the stakes 2 and the `end1 races 8' and :braces `9, shown in these figures,"may be used with `web plates fof @ber material, as wood, or web plates may *be lomitted yaltogether and the parts named :may be utilized as `a iskeleton body.

In Vthe modification LofV Figu the `corner plate i6 as y-we'll aswebplate '11 lhas 4its greatf 75 est thickness at the point 10 on a level with the car floor, tapering from this point both upwardly and downwardly.

The end braces 8 are shown as made u of side flanges 11 and end ianges 12. he 80 central portion of the brace is struck up into a rib, as shown at 13, which rib, as shown, terminates short of the ends of the brace though it may be coextensive with the brace, and 1s preferably higher at its center than 85 at its ends. The brace is shown bent at an angle to the length of the brace so as to lap past the ends of the car. As indicated in Figs. 6 to 8, the metal of the brace, both of its fianges and its rib is thicker at the center than toward the ends, thus producing additional strength of the rib where the greatest bendin stresses occur. The features of constructlon of the car body shown on the drawings, Without reference characters, merely indicate the usual construction of a car and form no part of'the present invention.

The arrangement of metal according to my invention will produce a car body of the usual weight but much stiffer than the old arrangement and will, moreover, produce a car body which will have a longer life under corrosion due to the fact that there is more metal to be corroded away at the points where greatest corrosion occurs than is the case with the usual arrangement. Moreover, with a car body of the usual weight ldue, to its,V additional. effective stren and stilnessfa lighter underframe may be used.

I claim as n1 invention- I 1. A car stilpening member comprising a central rib portion and fianges, the height of the rib and the thickness of material of boththe rib andthe langes being greater in" the: region of greatest expected bending stresses.

2. A car body comprisino web plates, and stakes the metal of which each of said members is composed being thickest near its lower portion and decreasing in thickness toward its upper portion.

A car body comprlsing web plates, and stakes each of said members being thickest in' the portion at the approximate level of the floor of the car and of decreasing thickness both above and below this plane.

1 4; A car body comprising, in combination,

I a corner member having its greatest thickness at its lower portion and which diminishes in thickness toward its upper portion, and an end brace attached to said corner member comprising flanges and a longitudinal raised central portion, the material of the flanges and of the raised orton being thickest opposite the center of t e end of the car.

5. A car body comprising, in combination,

1 a corner member Whose thickness both up- Ward and downward tapers from a maximum at the approximate levelof the Hoor ot' the car, and end braces attached to said `corner member comprising a Harige portion lapped about the corner member' and a longitudinal raised portion, the projection of the raised portion above the fianges and the thickness of material of both raised portion and flanges being greatest at the center of the car end.

G. A car body comprising structural members, the metalof said members being thicker at those portions where greatest stress is to be resisted, and tapering uniformly to portions Where less stress is to be resisted.

7. A car body comprising a web plate, the I netal of said plate being thickest at its lower portion and tapering uniformly7 to its upper portion. i v

8. A car body comprising a corner member the material of which the member is composed having its greatest thickness at its lower portion and which diminishes in thickness toward its upper portion.

9. A car body comprising an end brace having flanges and a longitudinal raised portion, the material of Which the raised portion and the fianges are composed being thickest at the central portion of the brace.
